The 3D LED Cube is a really cool device that enables you to see in three dimensions, get some depth perception and has 512 LED's or 512 pixels. It is based on an arduino uno which is an Atmel AVR microcontroller on a development board with some standard interfacing pinouts that allow you to quickly assemble prototypes.
Step 1: 3D LED Cube Hardware
- The LED Matrix
- Control electronics for Columns
- Control electronics for Layers
By addressing the appropriate layer and column in the LED matrix, it is possible to switch a particular LED on or off or vary its intensity. For each of these sets of controls, we have an interface to the brain which is an arduino uno running an Atmel AVR microcontroller. The arduino uno is programmed via a USB port from a PC. The arduino uno brain (or AVR brain) contains standard interfacing pins which allow connection to the outside world and external devices.
